Product details Amethyst under polarized light
Amethyst under polarized light
Sixteen figures showing specimens of amethysts viewed under polarized light and exhibiting veined structures. Brewster notes in his text: 'The observations...are the result of an immense variety of experiments, which accidental circumstances put it in my power to make upon this interesting mineral. Having access to whole bagfuls of amethystine pyramids from the Brazils, in the possession of Mr Alexander, lapidary in Edinburgh, I have examined some hundred specimens.' Plate 10 from the paper 'On the effects of compression and dilatation in altering the polarising structure of doubly refracting crystals', by David Brewster, originally published in Transactions of the Royal Society of Edinburgh, volume 8 (1818) pp.281-286. Inscribed with figure numbers and bottom right 'W.H.Lizars Sculpt. Edinr..' Sir David Brewster (1781-1868) Scottish physicist was elected a Fellow of the Royal Society in 1815.
